Weight-increasing device for vehicle with friction coefficient on road surface of aviation airport

Abstract

The invention provides a weight-increasing device for an airport road surface friction coefficient car, comprising: a chute, a hanging groove, a T-shaped counterweight and a rubber sliding sleeve; An L-shaped connection seat is welded, and a mounting groove is opened on the connection seat; the bottom plate is rounded, and a threaded sleeve runs through one of the connection seats, which can simulate the left and right directions of passengers in the aircraft cabin The variation of the friction coefficient when not equal, the flexibility and practicability have been improved, and a weighted hanging structure for hanging and pulling the matched objects is installed at the bottom of the device. After the device is installed on the chassis of the test vehicle, the counterweight can be placed The parts are hung on the hanging structure to further improve the simulation performance. After the device is installed on the test vehicle, it can obtain different friction data for the detected runway coefficient under various conditions, so that the test vehicle installed on the test vehicle The coefficient of friction tester realizes diversified detection.

Description

technical field [0001] The invention belongs to the technical field of installation structure for the bottom surface of a road friction coefficient test vehicle, and more specifically relates to a weight changing device for an airport road friction coefficient vehicle. Background technique [0002] The coefficient of friction is the ratio of the frictional force between two surfaces to the normal force acting on one of the surfaces. It is related to the roughness of the surface and has nothing to do with the size of the contact area. According to the nature of motion, it can be divided into dynamic friction coefficient and static friction coefficient. Sliding friction is produced by the relative sliding of two objects in contact with each other. After the airport is completed, it is necessary to use a friction coefficient vehicle to carry a friction coefficient tester to drive on the runway to conduct friction tests on the runway. [0003] Based on the above description, i...

Problems solved by technology

[0004] In order to solve the above-mentioned technical problems, the present invention provides a weight-increasing device for the road surface friction coefficient vehicle of the aviation airport, so as to solve the problem that the chassis of the existing aircraft runway friction test vehicle is mostly a steel structure with a certain fixed value, and the weight of the vehicle body is also fixed. It cannot be adjusted, and when the actual aircraft taxis on the runway, there will be different numbers of passengers, so the friction between the aircraft and the runway will change. However, the friction test formula of the above structure obviously does not have the actual simulation performance. question
